DC4 was really great, even though LaToya and Latavia didn't really add much. The songs were mostly Beyoncé (and sometimes Kelly) featuring the other girls.

And even though Beyoncé was still the spotlight in DC3, at least there was space for Kelly and Michelle to shine. They created a great image as a group of 3.

Maybe if Destiny's Child will ever tour again, it should be DC3, with maybe the other 2 joining for a few songs in Houston.
